Embodiment
Hereinafter, describe with reference to the accompanying drawings embodiment of the present disclosure in detail.
Fig. 1 is the block diagram illustrating according to the configuration of the message handler of first embodiment of the present disclosure.Message handler 1 comprises reception & disposal part 1a and control section 1b, and external unit 2a can insert from outside message handler 1., integrated PC(personal computer) etc. for example, corresponding to message handler 1.
Reception & disposal part 1a processes to receive input signal information generated signal by execution.In addition, reception & disposal part 1a changes into unlike signal form by the signal format of the information signal of current positive output, to the information signal with unlike signal form obtaining is outputed to external unit 2a.
When control section 1b identification does not have normal executive signal to process for external unit 2a, and therefore produce signal and process when wrong, control section 1b generates and changes instruction, and sends the change instruction that so generates to reception & disposal part 1a.
For example, in Fig. 1, suppose that reception & disposal part 1a can export and has four kinds of signal format # 1 to arbitrary information signal of #4, and external unit 2a can only process for the information signal executive signal with signal format # 3.
When thering is the information signal of signal format # 1 and sent to external unit 2a from reception & disposal part 1a, because external unit 2a processes for the information signal executive signal with signal format # 3, so may can not process for the information signal executive signal with signal format # 1 by external unit 2a.
In the case, control section 1b identification signal is processed wrong generation, and sends for changing the instruction of signal format and arrive reception & disposal part 1a.When reception & disposal part 1a reception is issued to its change instruction, reception & disposal part 1a changes into unlike signal form (for example, signal format #2) by current demand signal form # 1, and output has the information signal of unlike signal form.
Repeat such operation, this causes obtaining the signal format of the information signal sending from reception & disposal part 1a, previously in the coupling between the signal format arranging external unit 2a.That is to say, until the signal format externally arranging in unit 2a before the signal format of information signal coupling, from control section 1b continuous wave output, change instruction, and therefore reception & disposal part 1a changes into unlike signal form by the signal format of information signal, and export the information signal with unlike signal form obtaining.Therefore, in the situation that the message handler 1 shown in Fig. 1 is final, from reception & disposal part 1a output, there is the information signal of signal format # 3, and therefore in signal format, obtain coupling.By carrying out such control, the mismatch between the possibility that becomes automatic compensating signal form.
Next, will the problem that will be solved by technology of the present disclosure be described.Be noted that in the following description, external unit 2a is called CAM2.Signal format is equally also referred to as form.Fig. 2 is the block diagram that the ios dhcp sample configuration IOS DHCP of FTV is shown.Existing FTV200 comprises RF(radio frequency) tuner 201, digital demodulation part 202, Video Decoder 203, liquid crystal panel 204, control section (CPU: CPU) 205 and antenna a1.
The electric wave signal input RF tuner 201 having received at antenna a1.The signal that 201 times conversions of RF tuner receive at antenna a1, and select and export the signal of wishing tuning channel.
Because scrambling is as the TS signal of program signal, so received while sending to its TS signal from digital demodulation part 202 as CAM2, CAM2 carries out descrambling (that is to say deciphering).TS signal after descrambling completes sends to Video Decoder 203.
At this, when the form of the TS signal of having exported from digital demodulation part 202, while mutually not mating with the form of the TS signal that can process in CAM2, TS signal is destroyed in CAM2 in some cases.In this case, the user that may become can not watch normal picture and listen to normal sound.In addition, in some cases by utilizing relatively old technology design CAM2 itself.Therefore, CAM2 can not receive the output format of some TS signals in some cases.
Note, digital demodulation part 202 is by the suitable operation output TS signal of actuating logic, and CAM2 is also by the suitable operation output TS signal of actuating logic.Therefore not, abnormal just as existing in both at circuit (digital demodulation part 202 and CAM2).
About phenomenon as above, in interoperability, there is no transmission and the reception of normal executive signal, wherein the form of the TS signal of output and mutually not mating from the form of the TS signal of CAM2 output in FTV200.As a result, produce extremely.
So far, in the situation that produce the mismatch between the form of TS signal, when receive from user inquiry time, representational local service reselects and is suitable for causing the form of the CAM2 of problem in FTV200 etc., thereby processes such situation.For this reason, from receive time point from user's inquiry to the time point of dealing with problems time-consuming.Therefore, wish more efficient solution.
In view of such situation is made technology of the present disclosure, and be therefore desirable to provide message handler, the signal format change method of using in described message handler, the program of using in described message handler and the image display device that shows image thereon, described message handler detects the data exception (mistake) producing in CAM2, and carry out to change according to the output format from digital demodulation part of carrying out under Optimal State and control, thereby the mismatch between automatic compensating signal form.
Next, according to second embodiment of the present disclosure, by for its application is provided to description according to the image display device of the function of the message handler 1 of first embodiment of the present disclosure.Fig. 3 is the block diagram that the configuration of image display device is shown.Image display device 5 comprises RF tuner 10, digital demodulation part 20, image processing section 30, liquid crystal panel 40 and antenna a1.Image display device 5 is for example corresponding to FTV.
Note, with the form configuration image processing section 30 of IC.Be configured to optimize about S/P conversion portion 31, Video Decoder 32, picture quality/sound quality processing section 33 of the information of the image after having decoded and sound and be configured to carry out the whole control section 34 of controlling, being all included in IC.
The electric wave signal having received at antenna a1 is input to RF tuner 10.The signal that RF tuner 10 times conversion receives at antenna a1, and select and output just at the signal of tuning hope channel.
TS signal after output I/F part 23 completes for error correction is carried out output interface and is processed.Particularly, output I/F part 23, according to be issued to its change instruction from control section 34, the form of digital TS signal is suitably changed into different-format, and output has the digital TS signal of different-format.The example of the format pattern of TS signal is described with reference to Fig. 4 to 7 after a while.
The S/P conversion portion 31 that image processing section 30 inside provide is converted to parallel signal by the serial TS signal that outputs to it from digital demodulation part 20, this parallel signal then send to the CAM2 of the groove (not shown) that inserts image display device 5.
Because scrambling before, as the TS signal of program signal, is processed as signal in the processing of the TS of this reception signal so CAM2 carries out descrambling.Serial TS signal after scramble process completes sends to Video Decoder 32 from CAM2.
Note, if be parallel signal from the output signal of CAM2, between CAM2 and Video Decoder 32, provide so the composed component that is configured to carry out parallel/serial conversion.Therefore the TS signal, having obtained by parallel/serial conversion sends to Video Decoder 32.
For example, FEC part 22 has such mechanism, wherein when the signal that sends to it comprises error message, and proofread and correct while processing for error message execution error when FEC part 22, provide and represent that error message fully proofreaied and correct or still left over the wrong label information that surmounts correction.For this reason, control section 34 is processed by periodically carrying out poll, carries out for receive the processing of information from FEC part 22.
Similarly, Video Decoder 32 also has mistake existence or the non-existent mark that representative is wherein just comprising in the information of carries out image processing.Therefore, control section 34 is carried out for periodically receiving the processing of this information.
Note, with regard to the flow process of the TS signal about in image display device 5, TS signal is from output I/F part 23 interim input picture processing sections 30, and by 31 transmission of S/P conversion portion to be input to CAM2.The scrambling of carrying out for sponsored program before descrambling in CAM2 is processed, and then TS signal turns back to image processing section 30.After predetermined process in TS signal experience Video Decoder 32 and picture quality/sound quality processing section 33 in both, corresponding to the image of TS signal, be finally presented on liquid crystal panel 40.
Next, the form of TS signal is described with reference to Fig. 4 to 7.With regard to the form of the TS signal from 20 outputs of digital demodulation part, depend on that the structure of equipment exists various forms.
Fig. 4 to 7 is respectively the example of the format pattern of TS signal.TS signal s1 shown in Fig. 4 is the packet signal that wherein comprises signal TSCLK, TSSYNC, TSDATA and TSVALID, and has parallel form.
TSCLK is clock signal.TSSYNC is synchronizing signal, and first or byte of indication TS grouping.TSDATA is data.
TSDATA wherein comprises the parity check of data and 16 bytes of 188 bytes.In the case, after the data of 188 bytes, add the parity check (may have the non-existent situation in parity check interval) of 16 bytes.
TSVALID is the signal of the live part of representative data.For example, wherein to remain on the data of H level be effectively to TSVALID, and the data that wherein TSVALID remains on L level are invalid.
Note, the packet gaps of some positions or some bytes is followed parity check.After the end at parity check interval, by the grouping of the next TS signal of output.
TS signal s2 shown in Fig. 5 wherein comprises signal TSCLK, TSSYNC, TSDATA and TSVALID.TS signal s2 is data, the parity check of 16 bytes and the data of packet gaps that wherein comprise 188 bytes, and has serial form.TS signal s2 shown in Fig. 5 has such form, even wherein when TSVALID remains on H level, also stop the output of TSCLK for invalid data, and remain on L level for interval (byte gap) TSCLK of invalid data.
TS signal s3 shown in Fig. 6 wherein comprises signal TSCLK, TSSYNC, TSDATA and TSVALID.TS signal s3 is the packet signal that wherein comprises the data of 188 bytes, and has serial form.In the situation of TS signal s3 shown in Figure 6, TS signal s3 has such form, although wherein for invalid data continuous wave output TSCLK, TSVALID remains on L level for the interval of invalid data.
TS signal s4 shown in Fig. 7 wherein comprises signal TSCLK, TSSYNC, TSDATA and TSVALID.TS signal s4 is the packet signal that wherein comprises the data of 188 bytes and the parity check of 16 bytes, and has serial form.In the situation of TS signal s4 shown in Figure 7, TS signal s4 has such form, wherein for invalid data, stop the output of TSCLK, and for the interval (byte gap) of invalid data, TSCLK remains on H level and TSVALID remains on L level.
The form of the TS signal of exporting from digital demodulation part 20 as mentioned above, adopts various types of forms.In the situation that exporting TS signal to thering is parallel form (with reference to Fig. 4), in the situation that exporting TS signal to thering is serial form (with reference to Fig. 5 to 7), or the in the situation that of indivedual form, for clock signal (TSCLK), data (TSDATA) and control signal (TSSYNC, TSVALID), also there is various ways.These forms are according to the change that arranges in the output I/F part 23 of digital demodulation part 20.
Next, with reference to Fig. 8, for the operation of the format conversion of TS signal, provide description.Fig. 8 is the flow chart of operation that the format conversion of TS signal is shown.
In the processing of step S1, control section 34 is carried out the detection of FEC mistake, and detects the existence of wrong generation on communication environments or do not exist.
At this, the transmitting fault information that the FEC part 22 being provided by digital demodulation part 20 inside has detected is transferred to control section 34.Control section 34 is based on being transferred to its transmitting fault information, determines that whether all errors of transmission in TS signal are calibrated or still leaves over the mistake that surmounts correction.
Because suitably upgrade transmitting fault information in FEC part 22 inside, so control section 34 is carried out the processing of introducing transmitting fault information for the interval with suitable.When control section 34 identifications are still left over error of transmission, in this processing and in subsequent stage, still leave over mistake, and finally to show on liquid crystal panel 40 and to occur from liquid crystal panel 40 images of output and the form of the noise sound.
In the case, not the generation that leads to errors of form mismatch just as TS signal and CAM2.Therefore, the processing in step S1 is returned in operation.On the other hand, when control section 34 identifications no longer exist error of transmission (all transmitting fault informations are calibrated), operation enters the processing in step S2.
In processing in step S2, control section 34 detects the error message of having transmitted from Video Decoder 32.
At this, when be included in image in TS signal and digital compression data (such as the MPEG2(motion picture expert group 2) form of sound about its data) in, while there are the form violation data of some kind, Video Decoder 32 can detect this situation by the error detection information based on existing in packed data form.Error detection information is such as comprising CRC(Cyclical Redundancy Check) code information etc.
When error message not detected by control section 34, think and in CAM2, carry out the processing of wishing.That is to say, think from the form of the TS signal of digital demodulation part 20 output, and CAM2 carries out the form of the TS signal of scramble process to it, mutually coupling.In the case, the processing in step S1 is returned in operation.
In the processing in step S2, while error message being detected by control section 34, although result is to determine not have FEC mistake, by Video Decoder 32, mistake detected.In the case, think in digital demodulation portion, divide 20 and image processing section 30 between CAM2 in produce mistake.
Therefore, although when there not being FEC mistake, but while mistake having been detected in the stage of the processing of carrying out in Video Decoder 32, to there is mismatch between the form of the TS signal of its execution scramble process in the form of the TS signal that control section 34 estimations are exported from digital demodulation part 20 and CAM2.Then, operation enters the processing in step S3.
When image display device 5 is during in proper handling state, conventionally, on signal path, produce wrong probability low.Signal path means the route of output I/F part 23 → S/P conversion portion 31 → CAM2 → Video Decoder 32.
Yet, also there is the probability of the external noise of accident etc. that produces some kind on signal path.Therefore, in control section 34, get rid of this chance failure, to be not regarded as the form mismatch between TS signal.
When form mismatch due in TS signal and CAM2 produces when wrong, do not produce accidental mistake, but stably or periodically from Video Decoder 32 transmitting fault informations.For this reason, when error message is transferred to control section 34 pre-determined number from Video Decoder 32, the form mismatch between control section 34 identification TS signals.
When control section 34 determines that the number of error count does not also arrive predetermined value, the processing in step S1 is returned in operation.When control section 34 determines that the number of error count has arrived predetermined value, operation enters the processing in step S4.
In processing in step S4, control section 34 arrives output I/F part 23 by the command for being different-format by the change of format of TS signal.
The form mismatch pre-determined number that control section 34 detects between TS signal, and therefore the form of the TS signal that can be processed by CAM2 is not mated in identification from the current format of the TS signal of digital demodulation part 20 outputs.
Then control section 34 sends for the instruction that is different-format by the change of format of the TS signal of current positive output and arrives output I/F part 23.Output I/F part 23, according to be issued to its instruction from control section 34, carry out the format conversion for TS signal, and output has the TS signal of different-format (that is, format).
